So after much internal and external deliberation I decided to pull the trigger this morning. I have purchased a brand new 6D w/ 24-105 f/4L.

I have not shot Canon since my second to last film camera and my recent experience with Nikon's customer service with my issues with a D600 I bought sold me on dropping Nikon.

I had the kit lens from with the D600 and a 50mm 1.8 only. I have a few DX lenses from with my D90, but they are of no matter.

I took this experience to jump ship back to Canon and now need a few recommendations.

I went with the kit as I got it for an almost steal and basically paid $275 for the lens, but I want to augment it a bit.

I shoot mostly family trips, landscape, and the occasional kids sporting event. (And maybe once every year or 2 an air show, but this kept me to the 6d instead of the 5d3 as I don't need the better af.)

I want to pick up a moderate reach telephoto and also a few good leans for shallow DOF shots as I like to use it in a lot of shots while traveling with the family.

What suggestions do you guys have as a whole? I am looking to spend about 2000-2500 on glass over the next 2 months but don't want to blow it all on just 1 lens. I also don't want something that is so heavy that when I take long trips over seas that would require a lot of walking would make me want to leave it at home or in the hotel.

What are the current thoughts on the Canon 70-200 f/4L IS USM?

What suggestions are there for zoom lens for shallow DOF? I would love a 70-200 f/28L II but they are just way to heavy for me to use while traveling with my Wife and 4 year old.
